From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Had trouble lifting off but finally lifted to hover. Moved backwards. Tail boom hit ground. Helicopter rolled over. (From .4) the helicopter was for sale, but was not airworthy, and had not been flown for 6 months. The owner had shown the helicopter to the pilot a week prior to the accident. The owner and the pilot performed a ground run, but the owner would not allow the helicopter to be flown. A week later the pilot flew the helicopter without the owner's permission, and without the owner present. Witnesses reported that the helicopter did not appear to be stable at any time in the repeated attempts at takeoff. On the third attempted lift off, the helicopter became airborne, moved forward, and climbed to an altitude of approximately 5 to 10 feet above the ground. It then moved aft and the tailboom impacted the ground. The helicopter then rolled right, and the main rotor blades struck the ground. During a period of 18 months, repeated attempts to have the pilot provide a statement, or complete and return the required national transportation safety board pilot/operator aircraft accident report form 6120.1/2, were unsuccessful.
